Abstract

A holding material (3,30) used for a catalytic converter having a catalyst carrier (1) shaped like a cylinder, a casing (2) for receiving the catalyst carrier (1), and the holding material (3,30) mounted on the catalyst carrier (1) and interposed in a gap between the catalyst carrier (1) and the casing (2), the holding material (3,30) including a molding of inorganic fibers shaped like a mat or a cylinder, wherein at least an exhaust-gas-inlet-side end portion (3A) of the holding material (3,30) is set to be smaller in basis weight than any other area of the holding material (3,30) over a predetermined axial length.
